FOUNTAIN SIGHT-FEED;

" Specification of Letters Patent.

Patented Aug. 13,1907.

Application filed DecemberZB, 1904. Serial No. 238,045.

To all whoin it may concern:

Be it known that I, CHRISTIAN O. HILL, a citizen of the United States ofAmerica, and a resident of Chicago;

in'the county of Cook and State of Illinois, have invented certain newand useful Improvements in Fountain Sight-Feeds, of which the followingis a specification.

. This invention relates to fountain sight feeds for force feedlubricators and like apparatus, and has for its object to provide asimple and eflicient structural formation and combination of parts,wherebya distinct view or indication is afforded of the minutequantities of fluid which are fed at frequent intervals through the.device, all as will hereinafter more fully appear and be moreparticularly pointed out in the claims.

Inthe accompanying drawings:Figure 1, is a front elevation of a fountainsight feed embodying the present invention. Fig. 2, is a'veitic'alsection of the same, at line :r-x, Fig. 1.

Similar numerals of reference indicate like parts in ',both views.

Referring to the drawingsz-l, is the trunk member of the sight feedprovidedwith necks 2, 3, and 4, for the attachmentpf the other portionsof the appliance.

5, is a cylindrical open sided tube or skeleton casing screwing at itslhwer end into the screw-threaded bore of the neck 2 of the trunk memberaforesaid. 6 is a cap screwing upon the upper end of said tube or casingand adapted to confine the hereinafter described view tube in place.

7 is the transparent view tube, which in the present improvement isclosed at its upper end, and open at its lower end. I

8, is an annular elastic washer interposed between the margin of theopen lower end of the view tube and the adjacent top surfaceof the trunkmember, and

adapted to insure a tight joint between the respective parts. 9, is anelastic washer interposed between the closed upper end of the View tubeand the confining cap aforesaid, and adapted to exert a yieldingdownward stress upon the view tube and maintain the same in proper 10,is a jet tube'attached to the upper end of the trunk member,and'extending up into the chamber of the view tube. In the preferredform of the present invention the upper end of the bore or passage ofsuch jet tube is deflected to one side, so that the discharge therefromwill .be against the inner wall of the view tube, and it has been foundfrom extended practical experiment that as so discharged a very distinctappe'zii'ance is had of the fluid as it strikes and spreads upon thesurface of the view tube.

11 is' the inlet passage and 12 the outlet passage formed in the trunkmember, and extending out through the necks 3 and 4 for connection withthe respective inlet and outlet pipes of the appliance, and it is withinthe scope of this part ofthe present invention to modify the directionand arrangement of such passages I as may be required or indicated by aparticular use of the appliances.

The present appliance is intended for use in connection with-that classof force feed lubricators in which one or more single acting pumpplunger-s are employed to force the lubricant at stated intervals to oneor more points of use.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent, is

1. A. fountain sight feed, comprising in combination, a trunk member, acylindrical open side casing secured there to, a cap screwing upon theupper end of said casing, a transparent view tube arranged in saidcasing and having a closed upperend and an open lower end, and a jettube arranged inside of said view tube and attached to the trunk member,the said trunk member having an inlet passage connecting with said jettube and an outlet passage connecting with the lower end of the chamber,substantially as set forth.

2. Aiountain sight feed, comprising in combination, a trunk member, anopen side casing secured thereto, a. transparent view tube arranged insaid casing and having a closed upper end, an open lower end, and avertical jet tube the bore of which at its upper end is laterallydefiected, said jet tube being arranged inside said view tube andattached to the trunk member and adapted to jet the lubricant againstthe vertical wall of the view tube, the said trunk member having aninlet passage connecting with said jet tube and an outlet passageconnecting with the lower end of the chamber of the view tube,substantially as set forth.

3. A fountain sight feed, comprising in combination, a trunk member, anopen side casing secured thereto, a trans parent view tube arranged insaid casing and having a closed upper end and an open lower end, and avertical jet tube the bore of which at its upper end is laterallydeflected, said jet tube being arranged inside said view tube andadapted to jet the lubricant against the vertical wall of the view tubeand attached to the trunk member, the said trunk member having an inletpassage connecting with said jet tube and an outlet passage connectingwith the lower ad or the chamber of the view tube, substantially as setIorth.

4. A fountain sight feed, comprising in combination, a trunk member, acylindrical. open side casing screwing intethe same, a cap screwing uponthe upper end of said casing,

a transparent view tube arranged in said casing and having I a closedupper end and an open lower end, elastic washers a ranged between theupper and lower ends of the view I ...he and the cap and trunk memberaforesaid, and a jet tube arranged inside of said view tube and attachedto the trunk member, the said trunk member having an inlet sageconnecting with said jet 'tube and an outlet passage connecting with thelower end of the chamber of the view tube, substantially as set forth. I

5. A fountain sight feed, comprising inicombination, a trunk member, acylindrical open side casing screwing into the same, a cap screwing uponthe upper end or said casing, a transparent View tube arranged in saidcasing and having a'closed upper end and an open lower end, elasticwashers tube and adapted to jet the lubricant against the vertical wallof the view tube and attached to the trunk member.

10 the said trunkmember having'an inlet passage connecting with said jettube and an outlet passage connecting with the lower end of the chamber0! the "iew tube, substantially as set forth.
